Title: Discharge lamp lightening device
Inventor: USAMI YUTAKA
IPC: H05B41/16
Filed: 1990-09-27
Abstract: PURPOSE:To reduce the size and weight of circuit components used therein by connecting a discharge lamp to a direct current power supply whose output impedance is high. CONSTITUTION:A transformer 32 is provided with a direct current power supply 33, of which primary winding 331 connected to an alternating current power supply 31, and a discharge lamp 35 is connected to a secondary winding 332, which magnetically couples relatively weakly with the primary winding 331, via a diode 34. In this case, the output impedance of a power supply 32 increases as the magnetic coupling between the primary winding 331 and the secondary winding 332 in the transformer 33 is weak. Thus, when the alternating current power supply 31 is applied, current does not flow instantaneously in the discharge lamp 35 so that the discharge lamp 35 can be steadily lit. Consequently, impedance elements, such as a resistor etc., to be connected between the diode 34 and the discharge lamp 35 can be eliminated, so that reduction in size and weight of circuit components can be performed.

Filed: 1987-10-14
Abstract: PURPOSE:To obtain an image with sharp contrast at the time of a color original by providing an operating mechanism which putting a filter of the complementary color to the high-sensitivity wavelength light color of a photosensitive body on and off the optical path of reflected light. CONSTITUTION:When the original is a color original, the filter of the complementary color to the high-sensitivity wavelength light color of the photosensitive body 2, i.e. a filter 24 of yellow for a photosensitive body 2 having high sensitivity in the blue area is put on the optical path 31 of the reflected light opposite slit glass 22. Short-wavelength blue light is therefore prevented from being transmitted and an image of a blue original part is formed without exposing the photosensitive body 2. Further, when the original is a normal black-and-white original, the filter 24 is put off the optical path 31 of the reflected light. Consequently, the quantity of the light is not decreased and excellent picture quality is maintained. Further, the filter 24 is put on and off the optical path 31 by driving a motor with a changeover switch, so the operation is automated.
